Lindsay Dean, BA, CAS

Regional Director of Compliance, Quality & Risk

Lindsay Dean, BA, CAS, is Regional Director of Compliance, Quality & Risk, supporting treatment programs across the Alsos Behavioral Health network. She brings more than 10 years in behavioral health and is a Certified Addiction Specialist with a bachelor's degree in psychology and a minor in personal health. Lindsay began her career in direct patient care as a mental health technician, crisis intervention specialist, and counselor — experience that shaped her understanding of how trauma affects a person's willingness to engage with treatment, and that still informs how she approaches compliance work. As she moved into senior leadership her focus shifted to building treatment programs that hold clinical quality and regulatory integrity together rather than trading one for the other. She served as Program Director at one of the largest opioid treatment programs in Colorado, leading multidisciplinary teams and expanding access to care. Her work now spans accreditation, quality improvement, and risk management across the network's facilities.

Hillary Guggenheim, PMHNP-BC, MSN-MHA, MAP, RN

Director of Nursing

Hillary Guggenheim, PMHNP-BC, MSN-MHA, MAP, RN, is the Director of Nursing at Sheridan Grove Recovery in Aurora, CO. She brings more than 20 years of nursing experience spanning leadership, emergency and acute care, behavioral health, substance use treatment, correctional healthcare, and forensic nursing. She is a board-certified Psychiatric-Mental Health Nurse Practitioner with graduate education in nursing leadership and healthcare systems, healthcare administration, and psychology. Her focus as Director of Nursing is patient safety, regulatory compliance, quality, and developing the nurses on her team — and she is particularly drawn to behavioral health and substance use treatment, and to improving care through evidence-based practice. Hillary describes her leadership style as collaborative and hands-on. She values open communication, accountability, professional growth, and the perspectives of the people closest to patient care. Outside of work she travels — preferably anywhere near the ocean — sews, takes on home projects, and spends time with her very spoiled pets.

She has worked as an HR Coordinator, HR Director, and HR Business Partner, and holds an associate degree in business from the Community College of Denver and a bachelor's degree in business from the University of Denver. Her view of the work is straightforward: helping people builds trust, and trust builds stronger communities.

Outside of work Tracy is happiest around good food, travel, and a household that includes three small dogs and a cat named Miracle.
